Every turbidity tester costs $ 250+, so how does this sensor is priced $ 15?

This sensor cannot be used as professional equipment due to the low-precision, you can use it in experimental project and laboratory measurements.

Is the dac pcb necessary if i just want to use it in analog mode with my arduino?

Yes, you need to simulate the pattern with A

Does this come with the cable for connecting to arduino?

It comes with a gravity 3-pin female cable, which will be easy to connect to our IO expansion shield, if your arduino is UNO, you still need to use three more male-male jumper wire.

will this work on 3.3V as well?

No, this analog turbidity sensor needs to operate at 5V.
